I lovingly call “them” our dead people. And they can leave us signs, like a penny, a dime or a quarter. Any symbol we know them by can be used. One lady knew it was her daughter, through cardinals or a butterfly. A sign will usually accompany a person so you know it is them. For instance, lily of the valley perfume for grandma or old spice for grandpa. A lot of times they can make things disappear & reappear when they want it to. When this happens there is proof life goes on. Or a song on the radio that was special to that soul. In some cases, a loved one can appear in a time of danger as a warning. They can visit on occasion especially on special ones, like anniversaries, birthdays, etc.
